A tantalum capacitor is a type of capacitor with parts made out of the metal tantalum. Because they offer several advantages over older and more standard aluminum capacitors, tantalum capacitors are becoming increasingly popular and are often included in newer circuit designs.

IdentificationA capacitor is an electronic component made out of two conductive plates separated by an insulating material. It is used to store energy.

Tantalum

Tantalum is a rare, hard, heavy, blue-grey metal. It is highly resistant to corrosion and is mostly chemical inert, making it a durable

metal for electronic components. Tantalum capacitors are made from a small amount of mostly pure tantalum powder.

Uses

Tantalum capacitors are used in situations where the capacitor must hold power for a longer period of time.

They are also used with power supplies and in environments that operate at high temperature.

Durability

Because of the way tantalum capacitors are constructed and the natural resistance to corrosion of tantalum,

tantalum capacitors are exceptionally durable. They do not have any parts that wear out with use.

Polarity

One disadvantage to tantalum capacitors is that they are polar devices. They can only operate with power

flowing through them in one direction, unlike some other types of capacitors.
